I was spreading manure this morning worked fine for the first few loads. Went to engage it again and it wont turn.It wont even let me move the lever. If you unhook the PTO shaft, the shaft on the tractor turns real slow. Then it will engage. But not under load. I suspose I have to take the rear houssing off huh?? Any help is appreciated. Rob

Rob; Unless your clutch pack is adjusted almost all the way up, I don't think I would go to the expense of rebuilding it. Unless you are doing an awful lot of real heavy PTO work with it, they will run forever. Usually when something goes, it is either a cotter key falls out of a pin, or a pin breaks.

OK, so the CNH dealer said that everything I want, clutches, a new o-ring and a bearing is no longer available. Now what??? They said they were checking with Downing?? tractor parts. Anyway, if I cant get them throught the dealer, where could I get some new parts? Or will I have to go through the boneyards?? Thanks for your help. Rob

Thank you Bradley. Unfortuneately I do alot of heavy PTO work with it. It was starting to slip last fall on the chopper. My manure spreader is also quite a strain on the old girl. It is a "slinger" type. My 770 died, so this is my only tractor. Thank you for the help.

Thanks guys. A link did fall out of the sleeve/yoke. I found it today in the bottom of the housing. Im going to see if I can get new links, and while it is opened, I am going to put new cluthes in there. Has anyone done this recently? Im looking at my parts book and it says seven bronze, and eight of the other. Then it says I should get a new backing plate too? I want to order the parts tomorrow. Any help is appreciated. Thanks. Rob

Is this a 400 or a 411B? If it is a 400 the pto clutch assy can be removed by removing the hyd pump, and the pto engagement fork and shaft then the four bolts that hold the bearing / seal plate and pull the whole assy out and put it on the bench, the only thing taking the rear housing off will gain you is a good look at the bull gears.

Due to the sudden failure, I would tend towards a linkage pin falling out. As Don states, this can often result in this type of sympton.

Hard to believe, but I actually had a pin fall out on a live power DC a few years ago. It acted somewhat the same as described, but it would go into gear somewhat, it just wouldn't engage enough to pull anything. Good Luck, Don

Massey Ferguson 35 (and up) Tractor Assembly Notes - by Jack Wetmore. These assembly notes are for Massey Ferguson tractors with a two stage clutch and 6 speed, 8 speed and mutli-power transmissions. I see a lot of discussion forum messages regarding damaged clutches from improper assembly. The objective is to have the engine and transmission slide together safely and easily until the gap between the two halves is less than 1/4", BEFORE tightening any of the bolts holding the two together. Using bolts to draw the two halves together will damage the PTO
